It's a bit frustrating.
While tending to the injured Valkyries the day ended before he knew it. By the time Sam came out of the plane the humans who had lost consciousness were starting to wake up. Fortunately, the whispers of madness didn't seem to be affecting them anymore, but just in case he had the Nephilim Cleansers take turns using their ability to avoid any more Fallen from appearing.
Speaking of the Fallen, all of them were restrained, drugged and put to sleep. The Nephilim were surprised to learn that there were humans who survived the war from two decades ago, but thankfully none of them seemed to react negatively to their presence, even offering to help keep an eye on them to allow the Valkyries to rest.
